Strange behavior on one phone. All IP phones on SV9100.

One extension cannot call a handful of long distance numbers.
- Can call most numbers with no problem.
- Call a 'problem' number, get a reorder tone.
- Call a 'problem' number from another phone and it rings.
- Some of the 'problem' numbers are in the same building, same prefix.

I've tried moving the phone to different switch ports, swapped phones, all the regular stuff. I have found that if I change the extension number in the phone, it works! I cannot see any differences in programming between the bad extension number and a good extension number.

I would like to keep the original extension number and figure out why this is happening.
Thanks for any ideas.

Look to see what CID you are sending. Some carriers will not accept override CID because of spam blockers.

I checked that too. 21-18 has the same number for the phone in question as the other phones that can call the problem number.

Earlier I had swapped phones, unregistered the bad phone, etc. I gave the new phone the same extension number and still problems. Don't know how much data the un-register process removes, but apparently not whatever is causing the issue.

So you just change the ext number? Same port correct?

Login to the phone. SIP user - extension number- enter new number - save and reboot. Same phone, same port, different extension. Works with a new ext number.

When this was first reported, I deleted the registered phone, swapped phones with another known good phone, put the original extension number in the new phone and still could not call those numbers.

Create a new COS for that phone and try turning off 20-08-13,14 and 15. Also is this SIP trunking and what processor are you using?

Well, kiss my *** !

First, to answer your questions Coral Tech: PRI trunks. CP20 cpu.

It is working now. Here is what I did. Removed the entry in 21-18, Calling Party # for Extensions. Called out and worked fine. Then put the number back in 21-18 and it worked fine. I thought there must have been an invisible character or something.

While composing this reply, I looked back at the program entry in PC Pro using an old database. I saw that I had made a typo in the area code for that extension. With the numbers all run together, I was difficult to see.

Coral Tech: Since that was your original diagnosis, you're allowed an "I told you so."

Thank you for your replies and support. I appreciate your efforts.

Kicking myself :-(
